Published in the international journal Sociology of Health and Illness, the study — a collaboration between the Departments of Health Sciences and Cancer Studies at the University of Leicester — traced what happened in 13 cancer trials.
Author Prof Mary Dixon-Woods of the University’s Department of Health Sciences said the information sheets were “poorly aligned with patients’ information needs and how they really make decisions about whether to join a cancer trial”.
“Some patients did find them very useful, but many others paid them little attention. They preferred to rely on discussions they had with their doctor to make up their minds.”
The study looked at information sheets from the time they were prepared by the researchers leading the trials, through being reviewed and approved by research ethics committees. The study interviewed 26 patients who were approached to take part in trials and were given the information sheets.
“We found that the research ethics committee examine information sheets very carefully. They are genuinely keen to make sure that patients are not misled in any way and that the information sheets are easy to read. They very often ask researchers to make changes to make sure they are suitable,” said author Dr Natalie Armstrong, Lecturer in Social Science Applied to Health.
The problem was that information sheets were trying to do too many things, the authors said. “They end up having many of the features of a legal contract. Patients often find them far too long and incomprehensible, and even intimidating. In fact, many patients believed that the information sheets weren’t really produced for their benefit at all, but were more about researchers and institutions ‘covering their backs’,” said Dr Armstrong.
One patient in the study commented: “There was a lot of jargon that didn’t really necessarily need to be in there. I think that there was a lot of information that sort of baffled you.”
The study concluded that rather than using standardised templates, it might be better to have a list of principles that could be used when writing information sheets. It could also be valuable to involve patients themselves in helping to write and review them, commented Dr Armstrong.
“But we also have to accept that patients may continue to make their decisions about taking part in trials based on trust in their doctor, no matter how well-written the information sheets are. We need to find ways to support doctors when recruiting to trials.”
